Steering the Absorption Configuration of Intermediates over Pd-Based Electrocatalysts toward Efficient and Stable CO Reduction.

Palladium (Pd) catalysts are promising for electrochemical reduction of CO to CO but often can be deactivated by poisoning owing to the strong affinity of *CO on Pd sites. Theoretical investigations reveal that different configurations of *CO endow specific adsorption energies, thereby dictating the final performances. Here, a regulatory strategy toward *CO absorption configurations is proposed to alleviate CO poisoning by simultaneously incorporating Cu and Zn atoms into ultrathin Pd nanosheets (NSs).

The Incidence and Clinical Characteristics of COVID-19 in Children With IBD During the Omicron Wave: A Single-Center Experience in China.

The pandemic of coronavirus disease 2019 (COVID-19) had a major impact on the health of people worldwide, including the pediatric inflammatory bowel disease (PIBD) patients. As no study has investigated the susceptibility and disease course of COVID-19 in PIBD patients after the end of zero-COVID policy in China, we conducted a retrospective cross-sectional study in our center. A cross-sectional survey enrolling PIBD patients has been completed by online survey, phone, and face-to-face assessment.

Bioinformatic identification of important roles of COL1A1 and TNFRSF12A in cartilage injury and osteoporosis.

Objective: The aim of this study was to identify the key regulatory mechanisms of cartilage injury and osteoporosis through bioinformatics methods, and to provide a new theoretical basis and molecular targets for the diagnosis and treatment of the disease.

Methods: Microarray data for cartilage injury (GSE129147) and osteoporosis (GSE230665) were first downloaded from the GEO database. Differential expression analysis was applied to identify genes that were significantly up-or down-regulated in the cartilage injury and osteoporosis samples.

Maximizing Output Energy via Suppressing Charge Loss and Increasing Load Voltage in Charge Extraction Process.

The effective collection of interfacial tribo-charges and an increase in load voltage are two essential factors that improve the output energy of triboelectric nanogenerators. However, some tribo-charges are hardly collected through one or multiple integrated side electrodes based on corona discharge, and their load voltages are limited by air breakdown in adjacent electrodes. In this study, a dynamic quasi-dipole potential distribution model is proposed to systematically reveal the mechanisms of interfacial tribo-charge loss.

Global temporal trends and projections of hepatitis B-related cirrhosis among adolescents and young adults from 1990 to 2035: an analysis based on the global burden of disease study 2021.

Background: Chronic hepatitis B and cirrhosis pose significant global health threats. Few studies have explored the disease burden and mortality trend of cirrhosis caused by hepatitis B virus infection among adolescents and young adults (AYAs, aged 15-39 years). This study aimed to assess the disease burden and trends.
